Greptile Overview

Greptile Summary

Added the React error pattern "resolveDispatcher() is null" to the auto-reload error list in FrontendEventExceptionState. This error typically occurs when React hooks are called incorrectly or there's a React state synchronization issue.

• Extends the existing auto-reload mechanism (introduced in #5922) to handle this additional error type
• When detected, the page automatically reloads once per cooldown period to attempt recovery from transient state issues
• Follows the same pattern as existing browser-specific null pointer errors (Chrome, Safari, Firefox)
• No changes to the core auto-reload logic or cooldown mechanism

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is a simple, low-risk addition of a single regex pattern to an existing list. It follows the exact same pattern as the three existing error matchers, uses proper regex escaping, and doesn't modify any logic. The auto-reload mechanism was thoroughly implemented in the previous PR (#5922), and this just extends the list of errors that trigger it.
• No files require special attention
